Hyperplastic gastropathy as a presenting manifestation of systemic lupus erythematosus

Ménétrier's disease presenting as recurrent unprovoked venous thrombosis: a case report

BACKGROUND

Acquired thrombophilia is a potential sequela of malignancy, chronic inflammation, and conditions characterized by severe protein deficiency (for example, nephrotic syndrome, protein-losing enteropathy). As such, venous thrombosis is often a feature, and occasionally a presenting sign, of systemic disease. Ménétrier's disease is a rare hyperplastic gastropathy that may lead to gastrointestinal protein loss and hypoalbuminemia. To date, reports of venous thrombosis associated with Ménétrier's disease are exceedingly scarce.

CASE PRESENTATION

We report the case of a 40-year-old white man who presented with unprovoked deep venous thrombosis, pulmonary embolism, and renal vein thrombosis. Upon receiving therapeutic anticoagulation, he developed severe gastrointestinal bleeding, and endoscopic evaluation led to a diagnosis of Ménétrier's disease. A laboratory workup revealed deficiency of protein C, protein S, and antithrombin III, as well as markedly elevated levels of factor VIII. He was determined to have an acquired thrombophilia as a direct result of Ménétrier's disease.

CONCLUSIONS

This case describes an acquired thrombophilic state in a patient with Ménétrier's disease and profound hypoalbuminemia. Although this association is rarely described, we discuss the probable mechanisms leading to our patient's thrombosis. Specifically, we posit that his gastrointestinal protein loss led to a deficiency of several anticoagulant proteins and a compensatory elevation in factor VIII, as occurs in nephrotic syndrome and inflammatory bowel disease. Of note, this patient's recurrent venous thrombosis was the initial clinical sign of his gastrointestinal pathology.

Acute onset of systemic lupus erythematosus with extensive gastrointestinal and genitourinary involvement

Lupus enteritis may occur as an acute presentation of systemic lupus erythematosus (SLE), and is not uncommonly associated with acute uretero-cystitis and/or hydronephrosis. Extensive involvement of the gastrointestinal tract from the stomach to the rectum in acute SLE is uncommon. We describe a 22-year-old Chinese female who presented with acute extensive gastrointestinal and genitourinary involvement who recovered following pulse intravenous methylprednisolone and cyclophosphamide. A high index of clinical suspicion is required to arrive at the diagnosis of SLE where only acute gastrointestinal and genitourinary manifestations are predominant, and other clinical, haematological and biochemical features of SLE are absent.

Ménétrier's disease of the stomach: a clinical challenge

Ménétrier's disease is a rare hyperproliferative protein-losing gastropathy of the gastric foveolar epithelium. Most common symptoms include epigastric pain with fullness and vomiting, and generalized peripheral edema with hypoalbuminemia. Radiologically, the wall of the gastric body and fundus is diffusely thickened, often with antral sparing. Giant rugal edematous folds are seen on gastroscopy, and histology of biopsy material shows diffuse foveolar hyperplasia with cystic dilatation of the glandular portion of the gastric mucosa in the absence of significant inflammatory infiltrate. The recent discovery of transforming growth factor α overexpression opens the way of epidermal growth factor receptor blockade with cetuximab as first-line treatment modality in severe cases of Ménétrier's disease.

Protein-losing gastropathy with hypertrophic gastric folds: endosonographic findings

We present a case of protein-losing gastropathy with hypertrophic gastric folds. A 38-year-old man was hospitalized for severe epigastric pain suggestive of hypoproteinemia. Endoscopic and radiologic examination revealed enlarged gastric folds on the greater curvature of the stomach. Endoscopic sonography revealed marked thickening of the second layer on the greater curvature of the stomach. Endoscopic mucosal resection was performed, and the diagnosis was hypertrophic gastritis. After prednisolone treatment, hypoproteinemia and the enlarged gastric folds of the stomach resolved.

Strongyloides Stercoralis Hyperinfection in Systemic Lupus Erythematosus and the Antiphospholipid Syndrome

OBJECTIVE

The Strongyloides stercoralis hyperinfection syndrome (SHS) may develop in individuals with asymptomatic infection receiving immunosuppressive treatment. This report summarizes current knowledge regarding SHS in patients with systemic lupus erythematosus (SLE) and associated antiphospholipid syndrome (APS).

METHODS

Two patients with active SLE and associated APS presenting with SHS are reported. Additional cases of strongyloidiasis in SLE were identified and reviewed.

RESULTS

Patient 1: A 34-year-old woman with SLE and APS characterized by active glomerulonephritis, stroke, and several hospital-acquired infections presented with vomiting and diffuse abdominal pain. Intestinal vasculitis was suspected, and treatment with methylprednisolone and cyclophosphamide was given. Response was partial. A gastric biopsy revealed S. stercoralis larvae. She received ivermectin and eventually recovered. Patient 2: A 37-year-old man with active glomerulonephritis and APS with recurrent thrombosis presented with digital necrosis. Necrotizing vasculitis was suspected and treated with immunosupressants. He suddenly developed respiratory failure secondary to alveolar hemorrhage and bronchoalveolar lavage was performed. The patient developed Gram-negative septic shock and died. The postmortem result of bronchoalveolar lavage yielded Strongyloides larvae. Nine cases of strongyloidiasis and the SHS in SLE patients reported in the literature were identified and reviewed. Five of these patients died; none had associated APS.

CONCLUSIONS

These cases suggest that the SHS can exacerbate SLE and APS, predisposing to Gram-negative sepsis and death. Immunocompromised patients need an early diagnosis and specific treatment of parasitic diseases and their complications. The SHS should be considered in the differential diagnosis of lupus complications in patients from endemic areas.

Investigations and management of gastrointestinal and hepatic manifestations of systemic lupus erythematosus

Gastrointestinal (GI) manifestations of systemic lupus erythematosus (SLE) are protean. Any part of the GI tract and the hepatobiliary system can be involved. Up to two-third of SLE patients develop GI symptoms at some stage of their illnesses. Clinical presentations of GI lupus are non-specific and can be difficult to differentiate from infective, thrombotic, therapy-related and non-SLE etiologies. Clinical acumen and appropriate endoscopic, biopsy and imaging procedures are essential for establishing the correct diagnosis. Acute abdominal pain in SLE patients can herald an intra-abdominal catastrophe and should be evaluated promptly. Surgical intervention should be instituted without delay if conservative management fails or when there is clinical or radiological suspicion of visceral perforation or intra-abdominal collections.
